COMBINED FOLDING BEDSTEAD AND CHAIR.

To all whom it may concern:

Be it known that we, Anvil) Enonnnnn'r Ens'rnoM and Onor Bnnxnxnn Annnnssox, merchants, subjects of the King of Sweden and citizens of Sweden, residing at llmea, in the Kingdom of Sweden, have invented certain new and useful Improvementsin a Combined Folding Bedstead and Chair; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to a bedstead, which can not only be folded together so as to occupy small space, whereby the transportation is facilitated, but also can be adapted to a chair by a single adjustment.

The invention is substantially characterized thereby that the bottom of the bedstead is divided transversally in two halves, which are pivotally connected to the side members, each consisting of a series of rods pivoted to and crossing each other, and that the said halves may be pushed together while maintaining their horizontal position, the inner ends of the halves resting upon a cross-rod at the middle of the bedstead. The one bottom half is at its outer end pivotally connected to a member, which is of about the same length and width as the said bottom half, and which when the piece of furniture is adjusted to form a bed, forms an extension of the bottom at the one end of the bed, while said member, when the device is adjusted to form a chair, rests upon the bottom halves and forms the seat. At the said end of the bed there is further arranged a frame, which when the device is adjusted to form a bed, serves as a support for the said bottom extending member, and which, when the device is adjusted to form a chair, is turned below the seat.

The sides of the bedstead, as above indicated, are lazy-tong arms, which may be folded together in the usual way and locked to serve as the sides of a chair. The bottom of the bedstead, however, is not composed of lazy-tong arms and does not fold, but consists of sections that slide over each other occupying in both positions the horizontal Specification of Letters Patent.

plane of the middle pivots of said lazytongs.

An embodiment of the present invention is illustrated on the accompanying drawing.

Figure l is a side elevation of the device drawn out or adjusted to form a bed. Fig. 2 is a plan view of the same. Fig. 3 shows the device adjusted to form a chair. Fig. 4 shows the device in folded position.

The two side members a of the device or bed consist each of a series of rods, which are arranged two by two and pivoted to' each other, the sides of the bed-frame thus constituting two series of lazy-tong bars. The side members a are connected with each other by means of transversal rods 1), 0, (Z. The bottom is divided transversally into two halves or sections 6, f, which slide upon each other for contraction and expansion retaining in both positions the horizontal plane of the middle row of pivots of the lazy-tongs. These sections, at some distance from their outer ends are secured to the rods (Z, I) respectively, while the halves c, f in the expanded position of the bed rest with their inner ends on the middle rod 0. All the rods 7), 0, (Z are turnable around their longitudinal axes, the rods being provided with pins h, which pass loosely through the side members and each connects two adjacent rods of the said members.

The one bottom half f is at its outer end pivotally connected to a member la, which is of about the same length and width as the bottom halves. This member 71) is in the expanded position of the bed swung out, so as to form an extension of the bottom of the bed, as shown in Figs. 1 and 2. In this position the member Z; is supported by a frame Z, which at its lower end is pivotally inserted between the side members (Z and at the upper end connected with the outer end of the bottom half f by means of chains m, which limit the outward movement of the frame Z, but allow an adjustment of the frame, so that the inclination of the member 70 can be varied as desired.

In order to prevent the bed from being extended or drawn out more than to the position shown in Figs. 1 and 2, in which the inner ends of the bottom halves rest upon the middle transversal rod 0, the transversal rods (Z, 5 are connected by means of cords a. Said cords pass through holes in all the rods 7), 0, cl and are provided with knots at the ends and on each side of the middle rod 0. These knots cannot pass through the holes.

The bottom halves consist of longitudinal ribs spaced from each other a distance, which is equal with or somewhat greater than the width of a rib, so that the bottom halves can be pushed together While maintaining their horizontal positions, the ribs of the one bottom half sliding into the spaces between the ribs of the other bottom half, as will be readily understood from Fig. 2.

At the one end of the bed there are two side arms a, which are pivoted to the side members respectively andv each provided with two recesses 1 and s. In the expanded position of the bed the recesses s engage the adjacent upper points 3) of the side members.

WVhen the bed is to be adjusted to form a chair the arms n are brought out of engagement with the points 39, and then the member is is swung inwardly over the bottom half f, so that it will rest on this latter.

Further the bottom halves e, f are pushed together, the side members contracted and the frame Z is turned inwardly below the bottom with its upper end, and finally the arms a are adjusted, so that the recesses r and s engage the points 39 and '0 respectively, as shown in Fig. 3.

The end of bottom section e adjacent the chair back :1: extends through said back and is provided beyond the same with a shoulder forming an abutment for the corresponding end of the other bottom section f, Fig. 3, when the two sections are contracted by sliding one over the other as in the latter figure. The halves e f thus folded or contracted extend at each end for about one fifth or fourth of their length beyond the rods (Z 71 Of course at the end carrying the shoulder the half a is slightly longer than half f. By the above construction a proper length is obtained for the seat as well as for the bed bottom. The bottom extending member 7a is approximately of the same length as said sections and protrudes also at one end throughback 00. Said member then rests on said sections and its cushioned upper side provides the seat of the chair as shown in Fig. 8.

When the bedstead is to be folded together into the position shown'in Fig. l, the bottom halves after the releasement of the arms Z are turned into a vertical position or nearly so, and then the side members are contracted.

The member 7a is preferably on the one side (lower side, Fig. 1, upper side, Fig. 3) provided with a cushion or the like 1 Also such a cushion or wall 02 is inserted between the side members at the upper part of the one end of the bed, said cushion serving as a back, when the device is adjusted to form a chair.

Claims.

1. A convertible bedstead and chair having folding sides, a back and two extensible and contractible sections arranged to slide in each other, one of said sections 6 at all times protruding at one end through the said back and the other section f also protruding through the said back when the said sections are contracted to form a chair bottom.

2. A convertible chair and bedstead having extensible and contractible sides and bottom, the said bottom consisting of two sections 6 f sliding in each other and one end of section 6 being provided with a shoulder 6 which serves as an abutment or stop for the corresponding end of section f substantially as set forth.

3. A convertible chair and bedstead having extensible and 'contractible sides and bottom, the latter consisting of two sections sliding in each other, a back and a bottom extending member 70 which is approximately of the same length as said sections and is adapted to be arranged immediately above the same when they are contracted to form a chair seat, the rear ends of said member and sections then protruding rearward through said back substantially as set forth.

In testimony, that we claim the foregoing as our invention, we have signed our names in presence of two subscribing witnesses.
